Red Streaks & Spots on Uvula???

I am having problems with my throat lately.
I noticed a couple of months ago I developed red spots and streaks running through my uvula (you know that hangy thing in the back of your throat).
I didn't have a sore throat or anything I just got it one day.
I've always had bad sinus drainage so I thought it had something to do with that.
Well last night and all day today I've had this feeling of pressure in the back of my throat and it feels kind of swollen to me, I looked in the back of my throat and its looks to be a little closed off, the opening in my throat isn't as big as it usually is I mean if that makes sense.
And those red patches and streaks on my uvula looks more noticeable, darker in color.
Can anyone tell me what this is from?
